| Abstract: |
| 【Objective】The contradictions between water supply and sediment reduction occurred in the water supply reservoir of sediment-laden river were analyzed.And the technical support was provided to lay down reasonable operational mode for this type of reservoir.【Method】Using the basic idea of flow sediment mathematical model and optimization theory,the couple model of water sediment coordinative optimized dispatch was built in the water-supply reservoir of sediment-laden river.And the model was applied to optimize and compare the operational mode of Tingkou reservoir which was a typical water supply reservoir in the sediment-laden river.【Result】The couple model of water-sediment coordinative optimized dispatch was successfully built in the water supply reservoir of sediment laden river.The model consisted of the dynamic programming sub-model for reservoir optimized operation and the calculation sub model of sediment erosion deposition.Through the transfer of parameters and data,the couple model was formed as the definite conditions were influenced.The couple model was applied to optimize and compare the operational mode of Tingkou reservoir.The results-showed that the following operational mode was reasonable to Tingkou reservoir,that is storage operation but low water desilting at the right time of flood season.【Conclusion】The model had strong rationality and wide applicability.An effective way was provided to solve the problem of water-sediment coordinative optimized dispatch in the water supply reservoir of sediment-laden river. |
